Valve flow is streamlined with low resistance.
2. The opening and closing part is controlled by the medium itself to prevent backflow.
3. The sealing pair is advanced and reasonable. The sealing surface of the valve disc and the valve seat is welded by iron-based alloy or silicon tartar cobalt-based carbide, so it has the advantages of wear resistance, high temperature resistance, corrosion resistance and scratch resistance. . And it has a long service life.
4. The product can be used in various pipe flange and flange standard and flange sealing types to meet various engineering needs and user requirements.
5. There are a wide variety of valve bodies. Gaskets can be reasonably matched to the actual situation or user requirements and can be applied to a variety of pressure, temperature and media conditions.
